Dear PO (and Nabil),
Good question - I have asked Mr FPJ himself....more than once...when we were haviing dinner.
No go! Those are clocks for the boutiques and well-regarded dealers....er...officially.
Of course, I am pretty sure that if you were a "whale" or big-time collector, you may be able to convince a sympathetic manager to send you one whilst waiting for delivery of your Grand and Petite Sonnerie
They are electric clocks and (trivia alert) currently, the only FP Journe perpetual calendar timepiece is an Octa wall clock. The Reserve de Marche indicator is fixed at 96 hours. The three hands move and the date is electronically synchronised to indicate correct date......... perpetually.
Regards,
MTF
